Manufacturers of pre-cast concrete parts are often faced with the problem of how to offer cost-effective production even for small volumes of concrete. This is an issue, for example, in the production of precast parts for shafts for rainwater and sewage drain systems. The pre-cast concrete parts for this application are required in a variety of diameters and connecting angles and in a range of vertical inclines. However, there are solutions that are worth a closer look.

The Lainzer Tunnel is a railway tunnel in Vienna that is 12.8 km long and, from December 2012, will connect the Westbahn (western railway) with the Südbahn (southern railway) and the Donauländebahn railway. The purpose of this plan is to increase the capacity of the eastwest transit system.DOWNLOAD ARTICLE

Tunnel concreting train for building the slab track in the city tunnel of Malmö / Sweden

A slab track is being laid in the tunnel section with two individual six km tunnels. The sleepers are embedded in concrete and can absorb the vibration caused by high-speed trains in a better way due to having an extremely flexible insert. Maximum precision is required when the tracks are installed. The sleeper shoes that have been freshly embedded in the concrete must not be subjected to vibration. Even the slightest variations in the alignment of the tracks can result in the railway no longer complying with the original designs for high-speed travel.DOWNLOAD ARTICLE

Plans for the construction of a railway line in western China to Tibet were supported by Chinese politicians like Mao Ze Dong and Chou En Lai as early as 40 years ago. Since then the first segment of the Qinghai-Tibet railway line, 846 km long between Xining and Golmud (constructed 1958 - 1979), has been in operation for a long time. Further construction on the mammoth project was repeatedly interrupted during the 60s and 70s due to railway worker health problems, technical problems caused by permafrost and financial constraints. Construction of the remaining stretch of line, between Golmud and Lhasa, has now been resumed from both ends since June of 2001. Since more than 85 % of the route lies within an altitude range of between 4,000 and almost 5,100 m, the hardships imposed on men and machines are unbelievable. Even a PM truck-mounted concrete pump, type BSF 36.09, is keeping pace at heights of 5,000 m.DOWNLOAD ARTICLE

The construction of dams for the safe supply of water to the population and for agriculture is a tradition in many countries. In Ethiopia, where water supplies are relativelyplentiful, the construction of simple dams and surround of small lakes has been carried out by the state authorities since 1895. However, the dams constructed must be solid and a large quantity of concrete is required to ensure that large reserves of water accumulate. In view of the large quantities of material required, it is easy to understand that the building materials used must be as inexpensive as possible and also adapted to the conditions. This means that less cement (also to minimise the build-up of hydrationheat) and only a low proportion of sand and fine aggregate must be used – but with a considerable amount of oversized grain. As concrete pumps are not suitable for these extremely lean mixes, Putzmeister offers an alternative delivery system as part of its range.DOWNLOAD ARTICLE
